The information in this document is based on these software and
hardware versions:

Cisco MCS-78xx series servers

Cisco MCS-78xx Operating System (OS) V2000.x or later

The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.

Power-On-Self-Test (POST) is a series of diagnostic tests that run
automatically when the system is turned on (small program contained in the
BIOS). Most of the POST errors in this document are general. However, others
are related to Compaq-specific hardware.

POST checks these assemblies to ensure that the computer system
functions properly:

If POST finds an error in the system, an error condition is indicated
by an audible or visual message. If an error code displays on the screen during
POST or after you reset the system, use the instructions in the
POST Error Messages table found in this
document.

Note: Many of the actions listed require you to run Diagnostics or the
Compaq System Configuration Utility.

These utilities can be downloaded from the Compaq/HP web site per these
steps:

Fill out the exact model and OS of your server, then click
Locate Software.

The Software/drivers page for this particular model appears.

Click Utilities.

Download the Diagnostics Utility and System Configuration Utility
from this page.

Note: The blue LED which is located at the front and rear of an HP MCS
78XX server is called the Unit Identification light (UID). The UID is a feature
of all DL servers that allows the user to distinguish which server they are
working on in the rack. The UID can be lit from the CIM console, as well as at
the server by pressing either the front or rear UID button. Once lit, the LED
is blue in order to help the user identify the unit.

The Recommended Action column lists the steps necessary to correct the
problem. After completion of each step, run the Diagnostics program to verify
whether the error condition is corrected. If the error code reappears, perform
the next step, then run the Diagnostics program again. Follow this procedure
until Diagnostics no longer detects an error condition.

Error Code

Audible Beeps

Probable Source of Problem

Recommended Action

A Critical Error occurred
prior to this power-up.

None

A catastrophic system error, which cause the server to crash,
has been logged.

Run Diagnostics. Replace failed assembly as
indicated.

Unsupported Processor Detected
System Halted

1 long, 1 short

Processor not supported by current system ROM.

Check documentation for supported processors, and if supported,
remove the processor and update the system to latest ROM.

FATAL ROM ERROR: The
System ROM is not
properly programmed.

1 long, 1 short

ROM programmed in factory incorrectly.

Replace the physical ROM part.

101 - ROM Error

1 long, 1 short

System ROM checksum.

Run diagnostics. Replace failed assembly as
indicated.

101 - I/O ROM Error

None

Options ROM checksum.

Run diagnostics. Replace failed assembly as
indicated.

102 - System Board Failure

None

DMA, timers, or other system boards have
failed.

Replace the system board. Run the Compaq System Configuration
Utility.

Indicated drive has reported a SMART predictive-failure
condition and can fail at some time in the future.

1. If the drive is part of a nonfault-tolerant configuration,
back up all data before you replace the drive and restore all data afterward.
If the drive is part of a fault-tolerant configuration do not replace the drive
unless all other drives in the array are online.
2. Press F1 to resume.

1721 - Slot x Drive
Array - Drive parameter
tracking predicts
imminent failure. The
following devices
should be replaced
when conditions permit.
Do not replace
the drive unless all
other drives in the
array are online.
Back up data before
replacing drive(s)if
using RAID 0.

None

Monitor and performance threshold exceeded
condition.

Replace the drive when it is reasonable. The drive has not
failed, but Compaq recommends you replace the drive.

Indicates array accelerator configuration has been updated
automatically due to replacement of array accelerator (or controller) with one
having different memory size.

Press F1 to resume.

1727 - Slot x Drive Array-
New Logical Drive(s) Attachment
Detected. If more than 32
logical drives, this message
will be followed by:
Auto-configuration failed:
Too many logical drives.

None

Controller has detected an additional array of drives that was
attached when the power drive configuration information has been updated to add
the new logical drives. The maximum number of logical drives supported is 32.
Additional logical drives are not added to the configuration.

This message is normal following the initial configuration of
RAID 4 or RAID 5 logical drives. This POST message goes away and performance of
the controller improves after the parity data is initialized by ARM (an
automatic process that runs in the background on the controller).
